“…Considering the improved mixing of aeroramp injectors in supersonic flows, 79 a cavity flameholder coupled with aeroramp injectors were experimentally investigated by Olmstead et al 80 A direct comparison between the single angled injector and the aeroramp injector arrays was made. It was found that the operability reduced significantly for the aeroramp injector for all conditions tested, but the performance was virtually identical to that of the round injectors.…”

Cavities are widely used as flameholders in supersonic combustors due to their outstanding potential to stabilize combustion without excessive total pressure loss. A review of cavity-stabilized combustion for scramjet applications is provided in this article. The topics cover the fundamental problems and recent advances regarding cavity-organized combustion in high-speed flows, including combustion stabilization modes and mechanisms, flame stability analyses and correlations, combustion oscillations, and other related issues. Remarkable questions such as cavity-coupled fuel injection, flow and combustion coupling, optimal cavity geometry and scale, auto-ignition and flame propagation interactions, and unsteady effects are discussed. Then, an attempt is made to provide some guidelines for the future research of cavity flameholders.
